Say goodbye to our little friend, the unlimited 3G data plan for the iPad 3G + Wifi. Yes, it’s true, less than a month after rolling it out, AT and T has announced that they will be replacing the unlimited 3G data plan for iPad with a new, limited 3G data plan, known as the AT and T DataPro plan, effective Monday, June 7th. And the current $15.00 for 250MB per month plan has been reduced to 200MB per month under the new AT and T DataPlus plan. This means that if you are thinking of buying an iPad 3G, now is the time to do it, so that you can sign up for the unlimited data plan by Sunday.
